To @ZZ 207mm t r11/fry concern:

Beit known that We,FRANK H. DE GUERRE und WILLIE W. DE LANG, both citizens of the United States, residing in the city and county of Sen Francisco, und Ste-te ol Californie, have invented e new and useful Grete, of which the following is e specification.

Our invention relates to improvements in mnntelend other grntes,end will he understood by reference to the accompanying drawings and the letters marked thereon.

Figure l is n. perspective view; 2, n side elevation; Fig. 3, n transverse section, and Fig. 4 en under plan view.

The following is the construction of the inn ventien:

We forni the grate of any design to suit the requirements of the trede.

A represents the grate-front; B, the grate; C, the gratte pivots or journals; D, the du1nping-lever; F, the rest-noten for the hearing of the grate upon the duxnpinglever D. G represents the lever connecting joint; H, the guide-eye, and .l the dumping-lever eye.

The following is the operation: Willen the grate isto be dumped to tree it from einders and clean it, e hook or other instrument is in- Serterl in the lever-eye J, and the lever D is operated by tilting and pulling clown the back part of the grate end placing the same in the position shown in Fig. 2. Then the grate is to be simply shaken for the purpose of fliseherging the ashes, the elongated or oval form of the opening in the guide-eye E allows the grate B to be moved Snfieiently (longitufli l nelly) to sift out the ashes in the usuel Way. W' e prefer this motion, ns We are thereby ellowed to mnke n irni broad lateral hearing for thejoint G, that connects the lever D with the grate B. A

The ring 0r eye J forms the stop to prevent the grate from tilting higher than reqnired,end in consequence forms an importentfeatnre of our combination forming the dumping appnratus. down to a horizontal position, the front of the grate rests rmly upon the dumping-lever D, thus dispensing with the nesting of all stops upon the grate-frame, as the ring J and the lever D regulate the seme perfectly.

The lever D may he constructed either Straight or curved, es may be required; but we generally employ e lever more or less eurvefl.

We elaine, and desire lo secure by Letters Patent, is

The eornhination, with the grntefront hnving,r the depending eye llLof the grate B,jour

der fece the rest-notch Eend thelever D,piv oted to the under side of the grate, neer the forward end thereof, and extending through the notch F and eye H, substantially es Set forth.
